Error: write EPIPE with node.js and imagemagick

Question

I'm lost as to where this error is coming from, and I'm hoping you can help me. I'm new to node and am trying to resize an image with imagemagick:

var express = require('express'), 
fs = require('fs'),
gm = require('gm'),
imagemagick = require('imagemagick'),
var gm = require('gm').subClass({ imageMagick: true });
var app = express();


app.get('/', function (req, res) {
    console.log(__dirname + "/public/photos/4af1e720-a662-11e3-952c-61812ab60f67.jpg");
    imagemagick.resize({
           srcData: fs.readFileSync(__dirname + "/public/photos/4af1e720-a662-11e3-952c-61812ab60f67.jpg", 'binary'),
           width: "400"
    }, function(err,stdout,stderr){
           if (err) console.log(err);
           fs.writeFile(__dirname + "/public/photos/thumbnail/4af1e720-a662-11e3-952c-61812ab60f67.jpg", stdout, 'binary');
    });
});

I get the following:

I've already checked that the folder thumbnail/ exists, and that the image exists. Do you know what else could be going on?

You may need both imagemagick and graphicsmagick installed. That solved my issue.

Answer 2

Make sure both imagemagick and graphicsmagick are installed on your machine.

To install graphicsmagick on ubuntu,

$ sudo add-apt-repository ppa:dhor/myway
$ sudo apt-get update
$ sudo apt-get install graphicsmagick
